The question I'm really asking is that under Appendix 's' in the green book.
"Petrol" is a product of the kind sold as petrol to the general public, being mixtures of large numbers of substances produced in commercial refineries and sold through normal retail outlets.
Now every man and his dog has seen WRC and other crews pumping Carless, shell and Elf cans into there car. These fuel are FIA approved so I presume that is how they are used but is it "sold to the general public !!":dunno: .
Are you allowed to use these fuels in group n / modified ???:dunno:
I'm not trying to give stick to anyone using the fuel just establish weather it is legal to use or is it just a case of it's not really a rule


.
I do think it is good insurance on an expensive engine as the quality of the fuel can be guaranteed unlike forecourt products which are often not 98 or anything like it.
Just looking for some clarification ??
